Especially those high-level zombies made the three of them particularly uneasy. The "Evil Demon" that Fang Yuyang and Bai Ye encountered earlier had already made them feel threatened. If the number of such "Evil Demons" increases, how many humans will be able to survive?
It's important to know that as zombies advance in level, the zombie virus they carry mutates. If someone lower-ranked gets scratched by them, they will be infected with the zombie virus! If an ordinary person gets infected, they might just turn into a basic-level zombie, not immediately becoming a high-level zombie. But if an advanced superpower user gets infected, they might directly become a high-level zombie!
